In the header or upsetting machine herein illustrated in part, the wire line and thepush out line are in the same plane, preferably horiaontal, and the fabricating oi working die is in; v

a lower horizontal plane. i 1

In mechanism of this character workpiecesare severed successively froma-wire lengthqat the wire line;(cut-ofi die), andtnen carried to thepush-out line-.wherethe workpiece is projected into transfer mechanism and carried into, line with the fabricating die, v

The principalobject-of this invention is to provide a transfer mechanism independent of cutoff mechanism, that will receivethei'work-piece, grasp and hold it rigidly against relative movemerit, presentit in line with the fabricating die; or other tool, and release, its; grip or holdonthe-i workpiece as the workpiece? is partially projected? into the die asufficient-distancejtogsupportit; 2! Another object of this invention is to make? andthereafter. return for another workpiecei the transfer mechanism as lightas the labor thereon will permit and thereby aid in its" rapicl movement; to the end that thejspeed and output be increased} Afurther object merals indicate like parts in the several figures;-
